No dog should travel in a vehicle unrestrained. In an accident, even
a very small bump or sharp breaking can throw a dog forward onto
children or other passengers.A SAFETY HARNESS is ideal.

Use to type that clips onto the existing safety belt. Alternatively
a TRAVELLING CAGE can be used. If your dog is behind a properly
fitted dog guard a box muzzle is recommended - a frightened or injured
dog may behave uncharacteristically.
